Some of the most intense fighting experienced by Australian Forces during the Vietnam War occurred at Fire Support Bases Coral and Balmoral between May and June 1968. The Australians successfully held both bases, but at great cost. The Royal Australian Mint proudly commemorates the 50th anniversary of these events with a striking uncirculated 50 cent coin.During the “Mini-Tet” offensive mounted by the VietCong and North Vietnamese forces in May 1968, the 1st Australian Task Force deployed two battalions to an area 20 kilometres north of Bien Hoa city. The Australians established a number of fire support bases to provide firing points for artillery and mortars. These could cover foot patrols carried out by the infantrymen of 1RAR and 3RAR.One of these bases was Fire Support Base Coral; which was attacked several times between 13 and 22 May. In the first attack, the 1RAR mortar platoon position was overrun. With extensive air support, the attack was beaten off and the gun-pit recaptured. On 26 and 27 May the enemy attacked Fire Support Base Balmoral, but on both occasions were driven off by troops from 3RAR, supported by Centurion tanksWhen the fighting ended, 25 Australian soldiers had died and over 100 were wounded.Packaged in a display card with historical information about the Battles of Fire Support Bases Coral and BalmoralCoin’s reverse features a depiction of two soldiers manning a M2A2 Howitzer, along with a Centurion tank and Iroquois helicopterCoin’s obverse features the effigy of Her Majesty, Queen Elizabeth II sculpted by Ian Rank-BroadleyAustralian legal tenderMaximum Mintage 30,000Specifications: CuNi, 15.55g 31.51mm
